Now that manufacturers support their devices for 5+ years and ROMs are actually quite usable out of the box, the need for custom ROMs is much lower. Plus, some convenience apps require things like remote attestation, getting in the way of users. I suspect a significant chunk of the serious ROM user base is also lost to GrapheneOS these days.

Even Samsung is fine with a quick debloating session you can do through WebUSB these days. The only phones I'd really need a custom ROM on these days are those certain Chinese brands that stuff their phone with absolute garbage. Compared to the days where a custom ROM would be faster and updates would end after half a year, if they happened at all, I barely have a reason to use a custom ROM these days.
